Ectopic_Pregnancy_Pathophysiology Flashcards
Where do 97% of ectopic pregnancies occur?
97% of ectopic pregnancies are tubal.
Where is the most common location of tubal ectopic pregnancies?
Most tubal ectopic pregnancies occur in the ampulla.
Why are ectopic pregnancies more dangerous if located in the isthmus?
Ectopic pregnancies are more dangerous if located in the isthmus because of the risk of rupture.
What percentage of ectopic pregnancies occur in the ovary, cervix, or peritoneum?
3% of ectopic pregnancies occur in the ovary, cervix, or peritoneum.
What happens when the trophoblast invades the tubal wall in an ectopic pregnancy?
When the trophoblast invades the tubal wall, it produces bleeding which may dislodge the embryo.
What are the most common outcomes in the natural history of an ectopic pregnancy?
The most common outcomes in the natural history of an ectopic pregnancy are tubal absorption and tubal abortion.
What is tubal abortion in the context of ectopic pregnancy?
Tubal abortion is when the embryo and blood are expelled from the fallopian tube.
What happens during tubal absorption in an ectopic pregnancy?
During tubal absorption, if the tube does not rupture, the blood and embryo may be shed or converted into a tubal mole and absorbed.
What is a tubal mole in the context of ectopic pregnancy?
A tubal mole is a mass formed from the embryo and blood, which is absorbed if the tube does not rupture.
What is tubal rupture in ectopic pregnancy?
Tubal rupture is when the fallopian tube ruptures due to an ectopic pregnancy, causing significant internal bleeding.
